So, I was trading in WireCard and it was trading at 1,40. But trading 212 kept showing 1,36 and even went lower. So i’m still in the red when i should not be
I doubt it was the wrong price. There is a buy and a sell price. This difference is called spread. Check what you bought at and what the current sell price is.
If you click on WDI and go to history you should see the order and the exact time of buying and selling.
Are you saying you saw 1.40 outside of T212 whilst T212 was showing 1.36?
Might be worth noting that most sites and news sites etc operate on a 15 minute price delay so if you saw it outside the trading app you may have been seeing an old price
As the gentlemen above stated, it depends on the source that you are comparing the prices with as well as the direction of your trade.
External sources usually show mid-price, whereas your positions depend on the Bid/Ask prices, which are differentiated by the spread between them.
